help please...

Hi,

I am retrofiting a Tree Knee Mill, 220 JoruneyMan, it quite old but
still works fine.

as old it is has old servo motors from GOULD, I'll post more
detailed info from them. I would like to know if any of you know
where can I get info about those guys. I also found two steepers from
SIGMA, motor model is 21-4288D-23912, but have no other documentation
from them.

would like to know if any of you could share tech info from the
above motors.

the GOULD are ......

GOULD
Permanent Magnet Servo Motor.
CAT 16-0143-04
BACK EMF Ke 34.2 V/KRPM TACH 9.5 V/krpm
Torque Constant 2.88 LB-IN/AMP
Rated Current Ic Stalled 12.5 AMP.

thanks,
enrique.
